The Effect of Transcranial Direct Stimulation on Cognitive Functions of Healthy Adults
The Effect Of Transcranial Direct Stimulation Applied To The Dorsolateral Prefrontal Cortex And Posterior Parietal Cortex İn Cognitive Function, Mood And Proprioception İn Healthy Adults
Background: Transcranial direct current stimulation(tDCS) has been used to improve cognitive functions in healthy young adults.
Purpose: To investigate the effect of TDCS application on different cortex regions on cognitive function.
Methods: Sixty individuals aged 18-30 were included in the study. The participants were randomly divided into the left dorsolateral prefrontal cortex (Left DLPFC Group)(n=20), the right posterior parietal cortex (Right PPC Group)(n=20), and the sham group (Sham Group)(n=20). tDCS was applied for 20 minutes on weekdays for 2 weeks. The participants were evaluated in terms of cognitive functions with Neuropsychometric Test Battery before and after treatment.

Intervención / Tratamiento |
|---|---|
|
Comparador activo: LEFT DLPFC
The anode electrode of tDCS was applied to the left DLPFC and the cathode electrode was connected to the contralateral shoulder.
|
The intervention protocols were applied using tDCS (Teknofil TESsaNova).
All individuals received 2 mA of anodal tDCS for 2 weeks on weekdays.
All applications were done in the form of 20-minute sessions.
|
|
Comparador activo: RİGHT PPC
The anode electrode of tDCS was applied to the right PPC and the cathode electrode was connected to the contralateral shoulder.
|
The intervention protocols were applied using tDCS (Teknofil TESsaNova).
All individuals received 2 mA of anodal tDCS for 2 weeks on weekdays.
All applications were done in the form of 20-minute sessions.

Comparador falso: Sham
Placebo was applied by placing the electrodes in the right PPC and left DLPFC without applying current.
|
The intervention protocols were applied using tDCS (Teknofil TESsaNova).
All individuals received 2 mA of anodal tDCS for 2 weeks on weekdays.
All applications were done in the form of 20-minute sessions.

It measures the symptoms seen in depression such as emotional, cognitive and motivational. It includes 21 items determine a behavioral feature related to depression. Items are numbered from 0 to 3. The goal is to objectively break down the degree of symptoms. The total score of all answers is calculated as follows: 0 to 9 points: Minimally depressive symptoms 10 to 16 points: Mild depressive symptoms Between 17 and 29 points: Moderate depressive symptoms Between 30 and 63 points: Severe depressive symptoms |
